The guide plates (note Fig. 8) are formed circular and have a circular slot 16 andhave a radial guide 17 formed by perforating theplates as indicated at 19. and bending flanges 2O inwardly.

The'cross'he'ad construction which slides generally byfthe these guides designated numeral 21 and illustrated in Fig. 3 comprises an outer and an inner member 22 and 23. The

outer member has a topp-plate 24, two sides arms 25,.thes e having inwardlybentends 26. Theinner memberk has a bottom plate; 27, auf
